Inj extn musc/fasc/tend r idx fngr at wrs/hnd lv, sequela

This code signifies a long-term consequence or complication resulting from a previous injury to an extensor muscle, fascia, or tendon of the right index finger, specifically at the wrist or hand level. This could include conditions like chronic pain, stiffness, weakness, or functional impairment directly attributable to the original injury.

Apply this code when documenting a patient presenting with a current sequela (e.g., chronic pain, limited range of motion, scar tissue complications) of a past injury to the extensor structures of the right index finger. This code is appropriate when the initial acute injury has resolved, but its lasting effects are being treated or evaluated.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., chronic pain, scar contracture).
• Ensure documentation clearly links the current condition to a previous extensor injury of the right index finger at the specified level.
• Verify that the "S" seventh character is appropriate for a sequela, indicating a complication or condition arising as a direct result of a previous injury.
